A fruit seller had the same number of starfruits, lemons and kiwis at first. After 108 kiwis, some starfruits and lemons were removed, there were 119 fruits left. There were five times as many starfruits as lemons left. The number of kiwis left was 13 less than the number of starfruits. How many lemons were removed?

5 u - 13 |
119 |
Total number of fruits in the end
= 5 u + 1 u + 5 u - 13
= 11 u - 13
11 u - 13 = 119
11 u = 119 + 13
11 u = 132
1 u = 132 ÷ 11 = 12
Number of kiwis at first
= 5 u - 13 + 108
= 5 x 12 - 13 + 108
= 60 - 13 + 108
= 155
The number of lemons and kiwis at first was the same.
Number of lemons removed
= 155 - 1 u
= 155 - 12
= 143
Answer(s): 143
